Factors affecting volume change of myocutaneous flaps in oral cancer

After oral cancer resection with flap reconstruction, the volume of the flap decreases over time. The purpose of this study was to estimate the volume change in myocutaneous flaps and to identify the clinical factors associated with this volume decrease. Postoperative computed tomography scans and magnetic resonance images of 30 patients, obtained at 1, 6, and 12 months after oral cancer resection with myocutaneous flap reconstruction, were reviewed retrospectively. Changes in the volume of the flaps over time were assessed. The residual flap ratio was calculated using the flap volume at 1 month after reconstruction as the denominator. The residual ratios in relation to clinical factors were compared at 6 and 12 months using the Student t-test. Overall, the flap residual ratio was 78.1% (range 64.1–93.9%) at 6 months and 71.4% (range 48.8–87.2%) at 12 months. Hypertension, diabetes mellitus, and postoperative radiotherapy were significantly associated with volume changes at 6 months, and postoperative infection and decreased serum albumin levels were associated with volume changes at both 6 months (P=0.015 and P=0.001, respectively) and 12 months (P=0.026 and P=0.017, respectively). Flap reconstruction must be performed with postoperative flap atrophy in mind in order to preserve optimum speech and swallowing function.

Association Between Decreased Serum Albumin With Risk of Venous Thromboembolism and Mortality in Cancer Patients.

In cancer patients, reduced serum albumin has been described as a marker for global declining health and poor prognosis. Our aim was to investigate the association of albumin concentrations with the occurrence of venous thromboembolism (VTE) and mortality in patients with cancer. This investigation was performed in the framework of the Vienna Cancer and Thrombosis Study (CATS), a prospective observational cohort study. We included 1,070 patients with active cancer and assayed serum albumin from venous blood taken at study inclusion. Risk for occurrence of VTE was calculated in a proportional subdistribution hazard regression model with respect to competing risk of death and adjusted for cancer site, leukocyte count, estimated glomerular filtration rate, and cholinesterase. Patients (630 males [58.9%] and 440 females [41.1%]) were observed for a median of 723 days. During follow-up, 90 VTE events (8.4%) and 396 deaths (37.0%) occurred. The median albumin was 41.3 g/L (25th-75th percentile, 37.6-44.2). Patients with albumin levels below the 75th percentile had a 2.2-fold increased risk of VTE (95% confidence interval [CI] 1.09-4.32), as well as a 2.3-fold increased risk of death (95% CI 1.68-3.20) compared with patients with albumin above the 75th percentile. Decreased serum albumin levels in cancer patients were significantly associated with increased risk of VTE and mortality. Serum albumin, a marker of a cancer patient's overall prognosis, could be considered for risk assessment of important clinical outcomes such as VTE and mortality. Cancer patients are at increased risk of venous thromboembolism (VTE). In this prospective cohort study of 1,070 cancer patients, decreased serum albumin was a marker for risk of VTE and mortality, independent of kidney or liver function and inflammation markers. The study identified a group of patients with high risk of cancer-associated VTE and a reduced prognosis who may benefit from supportive therapy such as primary VTE prophylaxis.

Worse Neurological State During Acute Ischemic Stroke is Associated with a Decrease in Serum Albumin Levels.

High serum albumin levels during ischemic stroke (IS) decrease the risk of a poor outcome. This study aimed to determine whether serum albumin levels within the first days after IS correlate with radiological and biochemical markers of brain tissue damage. Fifty-six IS patients were enrolled into the study. Neurological examinations were based on the National Institute of Health Stroke Scale. Serum albumin levels and S100BB were evaluated using commercially available ELISA kits. The albumin decrease index (ADI) was calculated as the difference between serum albumin levels measured on days 1 and 10 of IS. All parameters were estimated on the 1st, 3rd, 5th, and 10th days of IS, and the volume of ischemic focus was measured on the 10th day. Mean serum albumin levels were decreased during acute IS. There were correlations between the ADI and mean S100BB serum levels (r = 0.36, p < 0.05), the volume of ischemic focus (r = 0.39, p < 0.05), and the patients’ neurological state when measured on day 10 of IS (r = 0.59, p < 0.001). A decrease in serum albumin levels during the acute phase of IS corresponds to a worse neurological state as a result of a large ischemic focus with intense catabolic processes.

The Nursing Diagnosis of risk for pressure ulcer: content validation.

Objective: to validate the content of the new nursing diagnosis, termed risk for pressure ulcer. Method: the content validation with a sample made up of 24 nurses who were specialists in skin care from six different hospitals in the South and Southeast of Brazil. Data collection took place electronically, through an instrument constructed using the SurveyMonkey program, containing a title, definition, and 19 risk factors for the nursing diagnosis. The data were analyzed using Fehring's method and descriptive statistics. The project was approved by a Research Ethics Committee. Results: title, definition and seven risk factors were validated as "very important": physical immobilization, pressure, surface friction, shearing forces, skin moisture, alteration in sensation and malnutrition. Among the other risk factors, 11 were validated as "important": dehydration, obesity, anemia, decrease in serum albumin level, prematurity, aging, smoking, edema, impaired circulation, and decrease in oxygenation and in tissue perfusion. The risk factor of hyperthermia was discarded. Conclusion: the content validation of these components of the nursing diagnosis corroborated the importance of the same, being able to facilitate the nurse's clinical reasoning and guiding clinical practice in the preventive care for pressure ulcers.

Prevalence of hypoalbuminemia and nutritional issues in hospitalized elders.

ABSTRACTObjective: to estimate the prevalence of hypoalbuminemia in hospitalized elders, related to socio-demographic variables, nutritional status and length of stay. Methods: crosscutting study with 200 patients hospitalized in a large hospital in the South of Brazil during three months. Evaluations, lab tests and interviews through questionnaires were performed. Results: the average albuminemia was 2,9 ± 0,5g/dL. Hypoalbuminemia was diagnosed in 173 subjects (87%) and was absent in 27 (13%) that have normal albuminemia (p=0,000). After six days of hospitalization, the prevalence of low levels grew significantly to 90% (p=0,002), average 2,7 ± 0,5g/dL. Using the Mini Nutritional Assessment, it was observed that 41 patients were malnourished and from those, 40 had hypoalbuminemia. Conclusion: the prevalence of hypoalbuminemia proved to be high, in approx. nine in ten elders, and the nutritional status and the length of stay proved to be related to the decrease of serum albumin levels. Thus, it is suggested that monitoring albumin levels should be done to evaluate the risk that the patient has to develop malnutrition and other complications during hospital stays.

Sarcopenia and Sarcopenic Obesity Are Prognostic Factors for Overall Survival in Patients with Cirrhosis.

Although the prognosis is known to be poor in cirrhosis patients associated with sarcopenia, the relationships among skeletal muscle, visceral fat, and the liver have not yet been thoroughly investigated. Therefore, the prognosis and its associations with body composition and the severity of liver disease were examined in patients with cirrhosis. The skeletal muscle mass and visceral fat area were measured in 161 patients with cirrhosis, the effects of body composition on the prognosis were analyzed, and any factors that contribute to changes in body composition were assessed. During the mean observation period of 1,005 days, 73 patients died. Patients with sarcopenia or sarcopenic obesity had a poor prognosis, and this difference was pronounced in the subset of patients classified as Child-Pugh class A. A decreased skeletal muscle mass was strongly correlated with decreased serum albumin levels. Sarcopenia is a common feature of advanced cirrhosis, and transitions were observed from normal body composition to sarcopenia and from obese to sarcopenic obesity. The body composition is a prognostic factor for cirrhosis, and a better body composition may be advantageous for obtaining a long-term survival in patients with cirrhosis.

Impact of Branched-Chain Amino Acid-Enriched Nutrient on liver Cirrhosis with Hepatocellular Carcinoma Undergoing Transcatheter Arterial Chemoembolization in Barcelona Clinic Liver Cancer Stage B: A Prospective Study.

In decompensated liver cirrhosis, hypoalbuminemia still persists even after they have been treated with branched-chain amino acid (BCAA) granules. We prospectively evaluated whether BCAA enriched nutrient switched from BCAA granules would increase the serum albumin level, and consequently extend the survival time after hepatocellular carcinoma (HCC) treatment. This study included 77 patients treated for liver cirrhosis with HCC. After the nutritional assessment, all patients initially received BCAA granules. In patients with unchanged or decreased serum albumin levels, BCAA granules were discontinued and BCAA enriched nutrient was started. Transcatheter arterial chemembolization (TACE) for HCC were performed in those with an improved Child-Pugh score. TACE were performed following the aggressive intervention with BCAA nutritional education in 54 of 77 (70.1%) patients. Finally, survival time was significantly extended in the TACE group (P<0.0001). Timely aggressive nutritional intervention in Barcelona Clinic Liver Cancer stage B HCC, namely, early partial replacement with BCAA enriched nutrient may consequently improve the treatment outcome of HCC.

Hyperuricemia Inversely Correlates with Disease Severity in Taiwanese Nonalcoholic Steatohepatitis Patients.

Background & AimsAsians are more susceptible to non-alcoholic steatohepatitis (NASH) as well as metabolic disorder than other ethnicities. We aimed to assess the interaction between metabolic factors and fibrosis in Taiwanese NASH patients.MethodsA total of 130 biopsy-proven Taiwanese NASH patients (94 males, age = 43.0 ± 13.0 years) were consecutively enrolled. Their demographic, metabolic profiles and histopathological manifestations were analyzed.ResultsTwenty-four (18.5%) NASH patients were non-obese. Thirty-three (25.4%) patients had significant fibrosis (F2) or more: 22 (16.9%) patients were of F2, whilst 11 (8.5%) patients were of advanced fibrosis (F3-4). The prevalence of metabolic syndrome, diabetes and hypertension were 60.8%, 39.4%, and 61.5%, respectively. There was a significant inverse correlation between hyperuricemia and fibrosis stages, ranging from 48.4% of F0-1, 33.3% of F2, and 9.1% of F3-4, respectively (P = 0.01, linear trend). Multivariate logistic regression analysis showed that a decreased serum albumin level (OR = 40.0, 95% CI = 4.5–300, P = 0.001) and normal uric acid level (OR = 5.6, 95% CI = 1.5–21.7, P = 0.01) were the significant factors associated with significant fibrosis.ConclusionsHyperuricemia inversely predicts fibrosis stages. Females might carry a more disease severity than males in Taiwanese NASH patients.

The Clinical Significance of Detecting Bacterial DNA by in situ Hybridization Method in Patients With Decompensated Liver Cirrhosis

Introduction: Patients with decompensated cirrhosis often suffer from various complications such as spontaneous bacterial peritonitis (SBP). However, it is difficult to diagnose SBP or bacteremia because bacteria in ascites or blood cannot be detected accurately by conventional culture method. It has been showed that the method using in situ hybridization (ISH) for detecting the gene of bacteria phagocytized by neutrophil in ascites is possibly useful to diagnose SBP within one day (Enomoto et al. J Hepatology 2012). It is thought that SBP is developed following bacteremia after bacterial translocation from the intestinal tract. Therefore we used the ISH method for blood samples taken from patients with decompensated liver cirrhosis and evaluated the significance of bacterial detection. Methods: Samples of peripheral blood and ascites were collected from 35 patients with ascites caused by liver cirrhosis. Blood samples were examined for bacteria using both conventional blood culture and ISH method. Samples of ascites were also evaluated by conventional culture simultaneously. The ISH method we used was the kit from Fuso Pharmaceuticals (Tokyo, Japan). Results: Eight of 35 patients were diagnosed with SBP. Six of the 8 patients showed positive results using the ISH method while bacteria were detected inonly one case byblood culture and one case by ascites culture. In 27 patients without SBP, 15 patients showed positive results using the ISH method while bacteria were detected in 4 cases by blood culture. The differences between 21 positive and 14 negative results by the ISH method were significant in presence of fever (16 / 5, p < 0.05) and decreased serum albumin levels (2.3 / 2.7, p < 0.05). However, there was no significant difference between administration of antibiotics, C-reaction protein level, and the presence of hepatocellular carcinoma. Notably, no patient who had a positive blood culture had a negative ISH result. Conclusion: The ISH method resulted in a higher positive rate of bacterial detection than culture in patients with decompensated cirrhosis. These results might implicate that “bacterial translocation,” which cannot be proved by conventional culture methods, really occurs. Therefore, it would be better for these patients with positive ISH results to be treated immediately. In patients with decompensated cirrhosis, the ISH method can be helpful for rapid diagnosis and early management of bacteremia and SBP.

Liver metastases from adenocarcinomas of unknown primary site: management and prognosis in 68 consecutive patients.

In this retrospective study, we aimed to evaluate the clinicopathological characteristics of the patients presenting with liver metastases from unknown primary site besides survival rates, treatment outcomes, and prognostic factors. In all, 68 patients followed-up at our center with adenocarcinoma of unknown primary (ACUP) metastatic to the liver between 2005 and 2013 were enrolled. All of the liver metastases were proven by liver biopsy and all yielded diagnosis of adenocarcinoma. Median age was 61 years (29-90) and most of the patients were male (male/female: 43/25). The liver was the only metastatic site in 2 (3%) patients whilst 66 patients (97%) had extrahepatic metastases. The most common extrahepatic metastatic sites were lymph nodes (89.7%), lungs (32.4%), bones (25%), peritoneum (11.8%), brain (4.4%), and adrenal glands (2.9%). Of all 68 patients, 39 (57.4%) were treated with chemotherapy. Median overall survival (OS) was significantly higher in ACUP patients treated with chemotherapy [12.5 months (95% CI 8.3-16.7) vs. 4 months (95% CI 1.2-6.8), (p = 0.026), respectively]. In multivariate analysis, ECOG (Eastern Cooperative Oncology Group) performance status (p = 0.009), chemotherapy (p = 0.024), serum albumin (p = 0.012), and serum CA 19-9 level (p = 0.026) at initial diagnosis were identified as independent prognostic factors influencing survival for the patients with liver metastases from ACUP. Patients with liver metastases from ACUP have poor prognosis and chemotherapy improves survival. Decreased serum albumin level, increased CA 19-9 level and poor performance status are independent poor prognostic factors.

Clinical Analysis of Pulmonary Nocardiosis in Patients With Autoimmune Disease.

Nocardiosis is an opportunistic infection that most commonly involves the lung; however, only a few case reports of autoimmune disease complicated by pulmonary nocardiosis exist in the literature.We conducted a retrospective analysis of 24 cases of both autoimmune disease and pulmonary nocardiosis at the Peking Union Medical College Hospital between 1990 and 2012.Fifty-two cases were hospitalized with nocardiosis, 24 of whom had at least 1 autoimmune disease before the diagnosis of pulmonary nocardiosis. The cohort patients consisted of 5 men and 19 women, with a mean age of 44.2 years. All were negative for human immunodeficiency virus. All but 1 patient had received immunosuppressants, including corticosteroids, cyclophosphamide, azathioprine, methotrexate, or hydroxychloroquine. Fever (87.5%), cough (83.3%), and sputum (79.2%) were the most common clinical manifestations. Ten cases were accompanied by subcutaneous nodules and/or cutaneous abscesses, and 4 had brain abscess. Half of them were lymphocytopenic. Thirteen of the 16 cases who underwent lymphocyte subtype analysis had decreased CD4+ T-cell counts. Nineteen cases had decreased serum albumin levels. Nocardia was isolated from sputum (13/24), bronchoalveolar lavage fluid (4/6), lung tissue (5/6), pleural effusions (3/5), skin or cutaneous pus (7/10), and brain tissue (1/1). The most common imaging findings were air-space opacities (83.3%), followed by nodules (62.5%), cavitations (45.8%), and masses (37.5%). Five were administered co-trimoxazole only, and the others were treated with 2 or more antibiotics. All 5 cases with skin abscesses and 2 of the 4 cases with brain abscesses were treated by surgical incision and drainage. None underwent thoracic surgery. Corticosteroid dosages were decreased in all cases, and cytotoxic agents were discontinued in some cases. Twenty-two cases recovered, and 2 died.Pulmonary nocardiosis associated with an underlying autoimmune disease showed a female predominance and presentation at younger age. Immunosuppressant therapy, lymphocytopenia, particularly low CD4+ T-lymphocyte counts, and low serum albumin levels may be disease susceptibility factors. Air-space opacities and nodules were the most common chest imaging features, and disseminated nocardiosis with lung and skin involvement was more common among them. Early diagnosis and anti-nocardial antibiotics with modulation of the basic immunosuppressive therapy were important for them.

Long-Term Mortality among Hospitalized Non-ICU Patients with Acute Kidney Injury Referred to Nephrology

Background: Epidemiological studies of acute kidney injury (AKI) have focused on patients admitted to intensive care units (ICUs), and several have studied hospitalized non-ICU patients, but analysis of patients referred to Nephrology is sparse. We analyzed factors associated with short- and long-term morbimortality among hospitalized non-ICU patients with AKI who were referred to Nephrology. Methods: A retrospective study with data prospectively collected from 170 non-ICU patients, with referral to the Nephrology Unit, recruited over a 4-year period, was performed. AKI was classified according to the criteria based on risk, injury, failure, loss of kidney function and end-stage kidney disease (RIFLE). Risk factors that could influence prognosis of AKI and long-term mortality were analyzed at admission. Early on, 1- and 10-year mortalities were correlated with AKI RIFLE class, clinical and demographic characteristics. Results: Most patients were >65 years, with multiple comorbidities and frequent drug intake history. Median Charlson score was 6. Twenty-five percent of patients with previously unknown chronic kidney disease (CKD) were diagnosed with CKD during the study. Dialysis was required in 13.5% of patients. Hospital deaths were 22.4% and significantly associated with older age, RIFLE class L, higher peak serum creatinine, oliguria and decreased serum albumin levels. One-year (38.8%) and 10-year (68.8%) mortalities were significantly associated with age, prior cardiovascular disease, prior CKD and RIFLE class L. According to the Cox proportional hazard model, age, prior CKD and RIFLE class L were independent risk factors of death at 1 and 10 years. Conclusions: AKI in hospitalized non-ICU patients is associated with high early and late mortality. This study increases our understanding of AKI among this specific population and can improve their management.

Prognostic value of serum homocysteine levels in elderly hospitalized patients

Increased serum homocysteine levels are related to vascular disease and increased mortality. The decrease of homocysteine is also associated with a worse prognosis in patients on hemodialysis; however, this relationship has not been well studied in other patients. Our goal is to study the prognosis of increased and decreased serum homocysteine levels in elderly patients admitted to a general internal medicine unit. We included 239 patients (121 women and 118 men; mean age, 78 years) in which we determined serum homocysteine levels and study its relationship with vascular risk factors, vascular disease: ischemic heart disease, ischemic stroke and peripheral arterial disease, nutritional status, creatinine, albumin, folate and B12 vitamin. Mortality during hospitalization of patients with homocysteine levels below 9 μmol/l was 33%, 9% for those with levels between 9 and 20 μmol/l and 17% for those with levels above 20 μmol/l. Low homocysteine values were related to increased comorbidity, higher degree of weight loss and decreased serum albumin levels. In a survival analysis using Kaplan-Meier curves, increased homocysteine was associated with increased mortality especially in patients with vascular disease. In elderly patients with multiple comorbidities, both decreased and increased serum homocysteine levels are associated with increased mortality.

Arterial blood pressure but not serum albumin concentration correlates with ADC ratio values in pediatric posterior reversible encephalopathy syndrome.

Posterior reversible encephalopathy syndrome (PRES) is a clinical-radiological entity affecting both adults and children characterized by neurotoxicity often in setting of hypertension coupled with distinct brain magnetic resonance imaging features. Decreased serum albumin level has been suggested to correlate with the presence of vasogenic brain edema in adult PRES. Serum albumin has thus been hypothesized to protect against neurotoxicity in PRES by reducing vasogenic brain edema through its role in maintaining plasma osmotic pressure and endothelial integrity. The purpose of our study was to investigate if such correlation between decreased serum albumin level and PRES-related vasogenic edema could be found in children. We conducted a retrospective study of 25 pediatric patients diagnosed with PRES. Underlying clinical conditions, presenting symptoms, blood pressures, and serum albumin levels at onset of symptoms were collected. Brain MR imaging studies were reviewed. We used a quantitative method to evaluate the degree of vasogenic edema by measuring apparent diffusion coefficient (ADC) values of the T2-FLAIR hyperintense brain lesions. No significant correlation was found between serum albumin level and degree of PRES-related vasogenic edema. A significant correlation was found between elevated blood pressure and degree of vasogenic edema in the temporal lobes (p = 0.02 and 0.04, respectively) but not in the other cerebral lobes or cerebellum. Our initial results suggest blood pressure, not serum albumin level, as a main biomarker for brain edema in children with PRES. Thus, our study does not suggest a protective role of serum albumin against PRES-related neurotoxicity in children.

P1327 : Attire: albumin to prevent infection in chronic liver failure

Background and Aims: Patients with cirrhosis are at a greatly increased risk of severe bacterial infection with survival directly related to extra-hepatic organ dysfunction. A defective innate immune response is considered to underlie this risk. There is however no medical strategy to restore immune competence in these patients. Elevated circulating Prostaglandin E2 (PGE2) levels contribute to immune suppression in acutely decompensated (AD) cirrhosis. PGE2 is more bioavailable because of decreased serum albumin levels in AD patients as albumin binds PGE2. The binding capacity of endogenous albumin is also known to be defective in cirrhosis. Human Albumin Solution (HAS), a safe and common intervention, could thus be repurposed as an immune restorative drug in AD patients. The primary aim of ATTIRE is to determine if raising serum albumin to >30 g/L in patients with decompensated cirrhosis will decrease rates of infection, extra hepatic organ dysfunction and death.

Risk Factors of Sepsis in Obstructive Acute Pyelonephritis Associated with Urinary Tract Calculi

Purpose: The aim of this study is to identify the risk factors for development of sepsis in patients with obstructive acute pyelonephritis (APN) associated with urinary tract calculi. Materials and Methods: Between January 2004 and December 2013, 73 patients with obstructive APN associated with upper urinary tract calculi were admitted to our institution. Medical records of 73 patients (14 men and 59 women, mean age of 57 years) were reviewed retrospectively. The risk factors for sepsis were analyzed using multivariate logistic regression analysis. Results: Of 73 patients, 37 (50.7%) developed sepsis. Old age and history of hypertension were more common in the sepsis group than in the non-sepsis group (p<0.001 and p=0.018). The white blood cell count, neutrophil count, plateletto-lymphocyte ratio, neutrophil-to-lymphocyte ratio (NLR), and C-reactive protein level were significantly higher in the sepsis group (p=0.011, p=0.001, p=0.042, p<0.001 and p=0.006, respectively). Lymphocyte count, platelet count, and albumin level were significantly lower in the sepsis group (p<0.001, p=0.008 and p<0.001, respectively). Multivariate logistic regression analysis indicated that old age (odds ratio [OR], 2.13; p=0.023), decrease in serum albumin level (OR, 4.27; p=0.041), and high NLR (OR, 3.83; p=0.037) were independent risk factors for development of sepsis. Conclusions: Elderly patients with obstructive APN associated with urinary tract calculi who have low serum albumin levels and high NLR should be treated carefully against development of sepsis.

Acute kidney injury in patients with human immunodeficiency virus infection.

Acute kidney injury (AKI) is an important cause of hospitalization and morbidity in human immunodeficiency virus (HIV)-positive patients. However, the data on AKI in such patients is limited. The aim of the present study was to analyze the incidence, causes and outcome of AKI in HIV-positive patients from our antiretroviral therapy centre. All HIV-positive patients were evaluated for evidence of clinical AKI. AKI was noted in 138/3540 (3.9%) patients. Of 138 AKI patients, 96 (69.6%) had acquired immuno deficiency syndrome and 42 (30.4%) were HIV seropositive. Majority of AKI patients belonged to AKI network (AKIN) Stage II (42%) or III (48.5%) at presentation. Prerenal, intrinsic and postrenal AKI were noted in 53.6%, 44.2% and 2.2% of cases, respectively. Hypovolemia (44.2%) and sepsis (14.5%) contributed to AKI in vast majority of cases. AKI was multifactorial (volume depletion, sepsis and drugs) in 39% of patients. Acute tubular necrosis (ATN) was the most common intrinsic lesion. Acute interstitial nephritis and diffuse endocapillary proliferative glomerulonephritis were noted in five and two cases, respectively. In-hospital mortality was 24.64%. Lower CD4 count, decreased serum albumin level and Stage 4 WHO disease were associated with higher mortality. At 3 months or more follow-up complete recovery of renal function, chronic kidney disease Stage 3-5 and progression to end stage renal disease were noted in 58.69%, 14.5% and 2.2% of cases, respectively. Thus, prerenal factors and ischemic ATN were the most common cause of AKI in HIV-infected patients. Recovery of renal function was seen in 59% of cases, but AKI had high in-hospital mortality.

Multiple logistic regression analysis of risk factors in elderly pneumonia patients: QTc interval prolongation as a prognostic factor

&#x0D; &#x0D; &#x0D; &#x0D; Background: Acute pneumonia is a serious problem in the elderly and various risk factors have already been reported, but the involvement of QTc interval prolongation remains uncertain. The aim of this study was to elucidate the prognostic factors for the development of pneumonia in elderly patients and to study the possible involvement of QTc interval prolongation.&#x0D; Methods: The subjects were 249 hospitalized pneumonia patients more than 65 years old in Aki-Ohta Hospital from January 2010 to December 2013. Community-acquired pneumonia patients and nursing care and healthcare-associated pneumonia patients were included in the study. The pneumonia severity index, vital signs, blood chemistry data and ECG findings were retrospectively compared using multiple logistic regression analysis.&#x0D; Results: 39 patients died within 30 days from onset. The clinical features related to poor prognosis were: advanced age, past history of cerebral vascular disease and/or diabetes mellitus, decreased serum albumin level, higher CURB-65 or PORT index scores and QTc interval prolongation. Patients showing a prolonged QTc interval had a higher mortality than those with a normal QTc interval. A prolonged QTc interval was not related to serum calcium concentration and/or treatment with QTc prolongation drug, clarithromycin or azithromycin, but related to age, lower albumin concentration and past history of diabetes mellitus.&#x0D; Conclusions: These findings suggest potential prognostic factors for pneumonia in elderly patients, including a prolonged QTc interval (&gt; 0.44 seconds).&#x0D; &#x0D; &#x0D; &#x0D;

Hepatitis C virus-related glomerulonephritis with acute kidney injury requiring hemodialysis that improved with virus removal and eradication using double-filtration plasmapheresis without interferon.

A 66-year-old, hepatitis C virus (HCV)-positive woman was admitted to our hospital with oliguria, systemic edema, and rapid deterioration of renal function. Laboratory examination showed increased serum creatinine and decreased serum albumin levels, complement activity, and cryoglobulin positivity. The HCV RNA genotype was found to be 1b, and the viral load was high. Kidney biopsy examination showed type I membranoproliferative glomerulonephritis with capillary deposition of IgM and C3, indicating HCV-related glomerulonephritis. After hospitalization, hemodialysis was immediately required because of uremia and oliguria. Her renal function did not improve despite corticosteroid therapy. To treat the increasing HCV load, virus removal and eradication by double-filtration plasmapheresis therapy without interferon was performed, since the patient was allergic to interferon therapy. This treatment improved renal function and allowed the withdrawal from hemodialysis. This report presents a case of successful VRAD without interferon therapy in a patient with HCV-related glomerulonephritis and acute kidney injury that required hemodialysis.
